Using an UNITL loop, I would like help creating a PowerShell program that does the following:

1. Shows an overseeing teachers name - Wood
2. Todays date
3. Asks for test scores from a final exam of 10 students.
   1. If a user fails, (< 60) then enter the students name and pass this out to text file called needsHelp.txt (5 fail - John, Tommy, Mira, Katie, and Laurel)
   2. If a user passes with flying colors (> 90) then enter the students name and pass this out to a text file called bestOf.txt (5 pass - Stephen, Dana, Grant, Luna, and Myles)
4. Scores must be between 0 and 100
5. Scores cannot be NULL
6. Have the user enter a sentinal value to quit
7. At the end of the program display the following:
   1. The overseeing teacher's name - Wood
   2. Todays date
   3. Average score
   4. Total number of As, Bs, Cs. (There should be a total of 10 scores)
8. Display lists of names of the students who didnt pass the test
9. Display lists of names from the bestOf.txt
